CONSTRUCTION OF RAIL'WAZY WAGONS AND THE LIKE.

Application filed September 19, 1925, Serial No. 57,472,

This invention relates to improvements in the construction of bodies ofpit tubs, railway wagons vans and the like, and consists in forming themof metal plates adapted to be held rigidly in position by improved formsof sliding joints.

The object of our said invention is to provide a body which can bequickly assembled or taken. to pieces for repairs, and of which yarioustypes and sizes can be constructed from metal plates of a. standard sizeor sizes, thus enabling their manufacture to be carried out on massproduction lines.

In describing this invention reference will be had to the accompanyingsheet of drawings upon which Figure 1 is a part sectional elevation of awagon body constructed according to our invention.

Fig. 2 is a section showing how the bottom plates are turned upvertically to form a connection to the side plates;

Fig. 3 is a section through a joint to be hereinafter described made upof four thicknesses of metal showing also a T-section member to behereinafter referred to;

Fig. 41 is an elaboration of the joint shown in Fig. 3 made up of sixthicknesses of metal;

Fig. 5 is a further elaboration made up of five thicknesses;

Fig. 6 is a section through the edge of a plate bent over on itself fourtimes;

Fig. 7 is a section through a joint made by bending two corner plates onthemselves and sliding them into one another;

F ig. 8 is a section through a joint formed by sliding a specially bentside plate over a T-section knee as will be hereinafter described.

In carrying out our invention we form the bottom of the wagon body ofany desired number of plates adapted to be joined by means of lap joint10, Figure 1, or by sliding U section joints of the kind described inour prior British Patent No. 16 1088.

The bottom plates 9 are turned up vertically round the edges to form aconnection to the side plates 1& as shown in Figure 2. The side platesare joggled, cranked or recessed as shown at 1 1 to receive thevertically turned up portion of the bottom plate, the two then beingbolted or riveted together giving a flush outer surface; alternative andin Great Britain September 19, 1824.

ly the joints may be similar to those hereinafter described.

The sides of the wagon are each formed of any number of plates, 14%, sayfor example three excluding the door, the plates being jointed togetherby means of a plain U-sec tion bend as shown in Figure 3, orelaborations; thereof as shown in Figures 4 and 5, thus giving astronger joint. The sides are reinforced by T-section knees 11 at eachside of the doorways. The ends of the side plates 14 are bent U-shape-toslide over the inner flange of the T portion as shown at let" Figure 8.The bottom of the U is projected beyond this flange and is recessed at14 to receive the door 13.

In assembling the wagon the bottom plates 9 are joined together vand theknees 1.1 are then fixed thereon. The side plates 14 extending from thedoorway to the end of the wagon are now slid on to the T-section knees11 forming the joint shown in Figure 8. The plate 146 below which thedoor is fitted is next slid into position forming the joint shown inFigure 3. This plate is preferably bent over on itself four times alongthe bottom as shown in Figure 6 to form a stiffening member where thedoor stops are lined to the wagon. The bottom plate where the door isfixed is turned under and then preferably bent over on itself threetimes.

At one end of the wagon an end plate 16 is preferably slid into flangesof each of the side plates 14 to form a four-ply joint Figure 7, or anelaboration of this joint as shown in Figures 4 and 5 may be employed.The complete end of the wagon is made up of any number, say for examplethree plates, which may he slid or lipped to each other by any desiredjoint.

The other end of the wagon may be formed as a door 17 and the sideplates suitably bent over and bolted or riveted to the T-section kneesas shown in Figure 1. The bottom plate is also turned up and bent over.The door 17 is suitably stiffened at 17 and hung on a roller bar 18passing through an eye bolt and through the top belt or turned over edge14 of the plates 1%; it may be conveniently secured by means of anexternal nut and an internal lock nut.

The top edges of the plates are bent over on themselves four times toform a stiii'ening top belt as shown inverted in Figure 6 and where thejoints in the plates make it desirable a tab may be left on each plateto it over the top edge of the adjoining plate, not shown upon thedrawings.

Diagonal braces as shown in dotted lines at 19, Figure 1, may be fitted.if desired, to prevent the side plates from buckling, also cleats 20,Figure 1 may be fitted into the fast end corners of the wagon.

Doors may be provided in the bottom if desired; further a woodenflooring; may be fixed on the top of the metal flooring and doorsprovided in the wooden floor, a suitable opening being left forclearance of the wooden doors. The number of bends or thicknesses ofmetal in the various joints or stiffening pieces may be increased orreduced as desired, and any of the plates may be thicker than the otherswhere greater strength may be required.

The body may be attached to a steel or wooden undertraine andconveniently bolted or riveted to same.

Having now described our invention what we claim as new and desire tosecure by Letters Patent isz A metal body, comprising a bottom made upof a plurality of plates united together, said bottom being turned uparound its edges, side plates having their lower edges ott'set inwardlythereby to fit within the turned up edges of the bottom, T-seetion kneessupported on said bottom for rein forcing said side plates, some of theside plates having along one of their vertical edges a U-shaped portionadapted to engage and slide over one of the flanges of said knees, thesaid U-shaped portion being wider than its engaging flange and recessedbeyond the flange "tor the reception of a door-forming; plate, theorganization being such that the exterior surface of the body issubstantially flush on all sides.

In testimony whereof we have signed our names to this specification.
